Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Update:
  Much to my delight, the engine started on the Very first flip, but stalled after a second. I thought it was to rich but after 2-3 attempts it was actually to lean. It likes to be quite rich (starting) then leaned out some after a minute of running. My engine ran very well for about 6-8 minutes and the governor functioned quite well....then the engine started hitting all the time and sounded like it was working under load.
  I shut it down and held the exhaust valve open and rolled the engine over by hand and can feel I now have some internal drag, it feels exactly like the gentleman on YouTube was speaking of on his engine, when he removed his piston he found his stock o-ring was poorly molded and had a lip on the parting line. He changed out to just a standard black Buna o-ring of good quality and his engine now runs Much better!
  I will open my engine and inspect my piston o-ring to see if I have the same issue.
  The photo shows I have my engine wood base clamped in a vise, it is Much better adjusting fuel mix with the engine firmly clamped.
  The photo is outside after dark and rather over exposed, it shows the engine as very bright red, my engine is not Burgundy but much darker red color than the photo.

To be continued....
